java - 如何使用 Ant 脚本调试 Java 桌面应用程序？

Question

我正在编译代码并生成桌面应用程序的 jar。但我无法调试代码。我想放置断点并使用 Eclipse F6 和 F5 函数逐步进行。有什么办法可以做到这一点吗？感谢您的帮助？我的 Ant 脚本如下:

<project name="R - 09 - tester">

<property name="app.name" value="Tester" />
<property name="app.version" value="2.0" />
<property name="dir.root" value="C:/.../trunk" />
<property name="dir.devel" value="${dir.root}/devel" />
<property name="dir.3rdparty" value="${dir.devel}/3rdparty" />
<property name="dir.deploy" value="${dir.root}/deploy" />
<property name="dir.binary" value="${dir.deploy}/bin" />
<property name="dir.class" value="${dir.deploy}/class" />


<property name="jar.xmlbeans" value="${dir.3rdparty}/xmlbeans/xbean.jar" />
<property name="jar.modelmesi" value="${dir.binary}/Model-Mesi-2.0.jar" />
<property name="jar.mesiapi" value="${dir.binary}/Mesi-API-2.0.jar" />
<property name="jar.mesimessages" value="${dir.binary}/Mesi-Messages-2.0.jar" />
<property name="jar.javaFX" value="${dir.3rdparty}/javafx/jfxrt.jar" />

<target name="init.property">
    <property name="manifest.created.by" value="..." />
    <property name="manifest.implementation.title" value="...." />
    <property name="manifest.implementation.vendor" value="..." />
    <property name="jar.mainclass" value="main.ApplicationMain" />
    <mkdir dir="${dir.class}" />
</target>

<target name="init.application" depends="init.property">
    <mkdir dir="${dir.class}/${app.name}" />
   <echo message="(OUTPUT) Application JAR File Name: ${app.name}-${app.version}.jar" />

</target>

<target name="clean.build" description="Clean Created Build Files" depends="init.property">
    <delete dir="${dir.class}/${app.name}" />
    <delete file="${dir.binary}/${app.name}-${app.version}.jar" />

</target>

            </fileset>
        </classpath>
    </javac>
</target>

<target name="build" description="Build the Application" depends="compile.application">

    </manifestclasspath>

    <jar destfile="${dir.binary}/${app.name}-${app.version}.jar" basedir="${dir.class}/${app.name}">
        <manifest>
            <attribute name="Created-By" value="${manifest.created.by}" />
            <attribute name="Built-By" value="${user.name}" />

    </jar>
</target>

<target name="rebuild" description="Rebuild the Application" depends="clean.build,build" />

<target name="run" description="Run the Application" depends="build">
    <java jar="${dir.binary}/${app.name}-${app.version}.jar"/>

</target>

Answer 1

您应该使用 <java> 启用远程调试标签。

<java ....>
 <jvmarg value="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5555"/>
</java>

现在运行您的 ant 脚本。它将启动 java 进程并等待，直到您与调试器连接到 porr 5555 。

如果您不想等待更改 suspend=y至suspend=n 。
